Montage of Microcapsules

Microencapsulation is a process by which very tiny droplets or particles of liquid or solid material are surrounded or coated within a continuous film of polymeric material. The microcapsules produced (typically within the 1-200microns in diameter range) can, depending on the core material (payload), be irregular in shape, simple spheres, multi-walled or contain multi-droplets.  In some cases a matrix particle can be formed whereby tiny droplets or particles become embedded within the hardened droplets of a polymeric material.

Microencapsulation Shapes

So why use microencapsulation:

  • To convert liquids or dispersion to solids
  • Separate reactive compounds
  • Provide environmental protection
  • Reduce volatility
  • Reduce flammability
  • Reduce toxicity
  • Improve material handling
  • Slow or controlled release of active ingredients
  • Targeted release
  • Improve storage stability
  • Mask taste or odours
  • Stabilise emulsions and dispersions
  • Provide micro-reactors

The range of commercial techniques fall into five distinct catagories:

  • Spray coating methods
  • Wall deposition from solution
  • Interfacial reactions
  • Physical processes
  • Matrix solidification

History of Microencapsulation

The process of microencapsulation began over 60 ago when Barret Green of the National Cash register company (NCR) was aksed to develop a product that would give multiple paper copies without the need for carbon-paper. He turned his attention to a process called coacervation and he was able to develop a solid gelatin sphere with an il-phase as core with colourless dye base dissolved. When the capsule was burst on striking of a type writer key of by a pen nib the dye was released onto a paper containing an acidic clay. The dye then bacame visible.
